' Specification of Letters Patent.

Patented June 1, 1909.

Application filed April 11, 1906. Serial No. 311,061.

To all whom it may concern:

Be it known that I, EDWIN F. BEUGLER, a citizen of the United States, residing at Buffalo, in the county of Erie and State of New York, have invented a certain new and useful Improvement in Machines for Driving Hoops onto Kegs, of which the following is a specification.

This invention relates to an improved machine for driving hoops upon kegs, such as nail kegs or the like, in which the hoops are driven simultaneously upon both ends of the ke or the like.

lue feature of the invention has reference to a novel hoop driving mechanism in which the driving arms are automatically closed around the keg as the hoop driving mechanism is operated to drive the hoops into place, and automatically opened as the hoop driving mechanism recedes from the keg after the hoops have been driven home.

Another feature of the invention has reference to a novel driving mechanism, so that both driving heads are given a simultaneous forward and back movement toward and from the keg.

The object of the invention is to produce a machine of simple, cheap and light construction, occupying a minimum of space and adapted to operate at a comparatively high rate of speed.

The invention also relates to certain details of construction all of which will be fully and clearly hereinafter described and claimed, reference being had to the accompanying drawings, in which,

Figure 1, is a front elevation of the im proved machine. Fig. 2, is an end elevation of the improved machine looking in the direction of the arrow V, Fig. 1. Fig. 3, is a transverse section through the machine on line a-a, Fig. 1, the keg support being omitted. Fig. 4, is a longitudinal section through the machine on line ?)b, Fig. 2, the eccentric mechanism being shown in elevation. Fig. 5, is a horizontal section through the machine on line 0-0, Fig. 1.

Fig. 14, is an enlarged detached inner end view of one set of hoop Fig. 15, is an enlarged detached view of one of the driving arms. Figs. 16 and 17 are opposite face views of one of the hoop driving plates. Fig. 18, is a section on line Fig. 13, two of the driving arms being shown in their normal or open position and the remaining arms being omitted. Fig. 19, is a view similar to Fig. 18, showing the two driving arms partially closed. Fig. 20, is an enlarged section through one of the driving arms on line hh, Fig. 15. Fig. 21, is an enlarged section on line ?Iz', Fig. 1. Fig. 22, is a detached plan view of the arm for retaining the starting lever in its position.

In referring to the drawings for the details of construction, like numerals designate like parts.

The machine frame.-The frame of the machine consists of two vertical end members 1 and 2, which are connected by longitudinal side members 3. The lower portion of each end member consists of two vertical legs connected near their lower ends by a transverse cross piece or brace 4; and the upper portion of each end member is substantially A shaped, see Fig. 2. The ends of the side members 3, are secured by bolts to the vertical end members 1 and 2, at about the point where the vertical legs merge into the A shaped portion, see Fig. 3. A horizontal opening is formed in the apex of each vertical end member and a longitudinal tie rod 5, has its ends screw threaded and passed through said openings, the rod being secured in place by nuts screwed upon its ends as shown in Figs. 1, 2, 3 and 4. Each of the cross pieces or braces 4, has a central vertical lug 6, provided with a horizontal opening through which the screw threaded ends of a lower tie rod 7 are passed. -The rod 7, is secured in place by nuts screwed thereon and against the opposite sides of the lugs, see Figs. 4 and 12. By this construction it will be seen that a frame is produced which is simple, light, and composed of few parts, is extremely rigid and occupies but a minimum of space.

T he driving mec7mns1m-T he driving mechanism for operating the hoop driving mechanisms is illustrated in Figs. 1, 2, 4-, 5 and 7, to which figures reference will be had in the following description. A transverse driving shaft 8, is journaled in bearings 9, formed on the inner side of the legs of the end frame member 1, and said driving shaft has a pinion 10, which meshes with a spur gear wheel 11, on acounter-shaft 12. This countershaft is journaled in bearings 13, formed in brackets 14, which are secured by bolts 15, to the outside of the leg portions of the end frame member 1. The spur gear 11, has a pinion 16, formed integral therewith and said pinion meshes with a spur gear 17, mounted on a main shaft 18, which is our naled in bearings 19, formed in the brackets 14, and almost vertically above the bearings 13. The driving shaft 8, is rotated by a pulley 20, loosely mounted upon a projecting portion of the shaft, the pulley being held against lateral movement in one direction by a collar 21, secured to the shaft by a set screw, see Fig. 7. The pulley is locked to the shaft to rotate the same, by a clutch mechanism which is fully shown in Fig. 7. A sliding sleeve 22, is mounted upon the end of the shaft so as to have a longitudinal movement on said shaft, but is prevented from independent rotation by two keys or feathers which Work in longitudinal keyways in the shaft, see Figs. 1 and 7. Atthe end of the sleeve nearest the pulley 20, are two oppositely extending lugs 23, in each of which is seated a pin 2%. These pins project laterally from the faces of the lugs and are adapted to engage with two similar pins which project laterally from the hub of the pulley 20, and so lock the pulley temporarily to the sleeve. The outer end of the sleeve 22, is reduced and a ring 26, is loosely titted upon said reduced portion and held in place by a collar 27. The ring has two oppositely extending pins, 28, adapted. to seat in the forked ends of a yoke lever 29, which securely fastened at its lower end to a longitudinal rock shaft 30. The rock shaft is preferably square in cross-section with the exception of its ends which are round. These ends are seated in vertical depressions in the outer ends of two bracket-like arms 31, extending from the foot of one of the legs of each end frame member, which form bearings for said shaft, see Figs. 1 and 7. The shaft is rocked to move the clutch sleeve into or out of engagement with the pulley, by

means of a hand lever 82, which is fastened at its lower end to the rock shaft and extends in a substantially vertical direction to within convenient reach of the operator, see Figs. 1 and T. The lever is moved in a direction toward or from the machine to rock the shaft and thus start or stop the machine, and is automatically locked in either position by a simple and etlicicnt device illustrated in Figs. 1, 5, T and By referring to Figs. 3 and 21. it will be noticed that the longitudinal side frame men'ibers are of channel bar cross section. It horizontal bar 33, has its inner end in the form of a. hook. which hooks over the inner edge of the lower horizontal portion of the frame member, and its outer end provided with a curved slot 34-. This bar is lo rated so that its outer end is in close proximity to the starting and stopping lever 32. and a bolt 35, is passed loosely through an opening in said lever and through the curved slot :51. A vertical pocket is formed in the bar near its rear end and a coiled compression spring 36, is seated in said pocket and exerts a pressure against the bottom surface of the side frame member, thus tending to depress the outer end of the bar, see Fig.

It will be seen that owing to the slope of the slot IL. the bolt 35, will be retained in either end thereof, by the downward tendency of the outer end of the bar and thus prevent the jar of the machine from involuntarily relcasing the. hand lever and operating the clutch. ll'hen the operator shifts the hand lever 32, the bolt riding in the slot, raises the end of bar against the tension of the spring so, until said lever is past the center, when the bolt slips into its seat. in the end of the slot.

The ec entric 'IHCC/IJ/llfS/It for opclwfiny HM 7200 driving nice/Mott's)..:\s before stated. the hoop driving meclmnisins are given a forward and back or reciprocating movement toward and from the keg. This is driven by means of a pair of eccentrics connected to a pair of levers supported at one end by movable fulcrums, and connected at their other ends to the hoop driving mechanisms. This mechanism is illustrated in 1, 2, 3, l, 5, 7, S and 12.

There are two separate sets of hoop driving mechanisn'ls each of which drives the hoops upon one end of the keg. These hoop driving mechanisms are duplicates, each consisting of a driving head; a. centering and shaping cone for accurately centering the keg and spreading the ends of the staves; and a plurality of driving arms having a radial movement.

The two sets of hoop driving mechanisms are slidably supported upon two horizontal extending bars and $38. which are supported by having their outer ends rigidly clamped in openings formed in transverse loo lilfi llll braces 39, in the A shaped portions of the end frame n1 amber 1 and 2. These braces are split and are drawn against the bars by clamping bolts as shown in Fig. 2.

The driving mechanisms are given a reciprocating movement on the bars 37 and 38 by a pair of eccentrics 40 and 41, mounted upon the main shaft 18. These eccentrics work oppositely to each other and have eccentric straps 42 and 43, which are connected by eccentric rods 44 and 45, to two levers 46 and 47 supported at their lower ends by movable fulcrum blocks 48 and 49. The levers 46 and 47, are each preferably constructed of two parallel bars having openings in their lower ends in which oppositely extending pins 50, projecting laterally from the fulcrum blocks fit. The parallel bars composing each lever extend upwardly and are separated from each other, the upper ends thereof straddling the hubs 51 and 52, of the driving heads 53 and 54. As shown in Figs. 1, 4 and 8, portions'of the sides of the hubs are cut away to form depressions in which the upper ends of the levers seat. The end walls of the depressions are shaped so as to provide a working point for the levers and so reduce friction.

A bolt 55, ties the upper ends of the bars composing the levers, and a roller 56, is supported by this bolt and rolls on the top surface of the hubs 51 and 52, see Fig. 8.

The ends of the eccentric rods 44 and 45, are secured to an intermediate point of the levers by fitting their ends between the bars comprising said levers, and securing them in place by bolts 57, see Figs. 3 and 8.

The fulcrum blocks 48 and 49, are supported by bars 58 and 59, and have a slight longitudinal movement against the tension of springs. These bars 58 and 59, have their outer ends passed through openings in the cross (pieces or braces 4 and their inner ends passe through openings in the fulcrum blocks. The blocks are adjustable on the bars and are locked in place by locknuts 60, screwed against both sides of the blocks, see Fig. 12. Heavy coiled depression springs 61, encircle the center projecting ends of the bar 58 and 59, said springs being held in place by spring capes 62, and screw nuts 63. Lock nuts 64, on the bars, screwed against the inner sides of the cross pieces or braces 4, prevent the outward movement of said bars, see Fig. 12. The fulcrum blocks are guided in a longitudinal direction and prevented from lateral movement by vertically extending forked projections 65, projecting from the top surface of the blocks and straddling the lower tie rod 7.

By referring to Fig. 7, it will be seen that the eccentrics 40 and 41, are cast in one integral piece of metal. This method is preferred as it obviates the possibility of one of the eccentrics slipping on the shaft'and so changing its position with respect to the other eccentric. Besides being secured to the shaft by a key, the eccentrics are rigidly fastened to the spur gear 17, by bolts 66, so that the real driving strain is borne by said spur gear instead of the shaft.

The hoop driving me0ham'sm.As before stated there are two sets of hoop driving mechanisms and as these sets are exact duplicates, but one set will be described, like parts on both sets being designated by like numerals except where it is thought necessary to distinguish between like parts on both sets to more clearly set forth the construction or operation.

In the following description, reference will be particularly had to Figs. 1, 3, 4, and 13 to 20 inclusive of the drawings to which atten tion will be frequently called.

The driving heads 53 and 54 are preferably formed as shown in Figs. 13 and 18 being circular in form and having central hubs 51 and 52. Each driving head has a plurality of radially extending Y shaped arms 67, which radiate from the central hub, and terminate at their outer ends in lugs 68, between which the driving arms are pivoted. A cross piece 69, connects the branches of each Yshaped arm to the branches of the adjacent Y shaped arm, said cross piece being located near the outer termination of the arms, and thus forms pockets 70, the purpose of which will be described farther on.

The centering and shaping cone is in the form of an annular ring having a cone shaped or beveled portion 71, a cylindrical portion 72, and an annular flange 73. This ring is connected to a central hub 74, by radial arms 75, said hub being loosely supported upon one of the bars 37 and 38, adj acent to the driving head, see Figs. 14 and 15. A plurality of equally spaced, diagonally extending radial arms 76, extend outwardly from the annular flange 73, the outer extremities of the arms being bentforward at about right angles to form hook portions as shown in Fig. 19. The radial arms 7 6, ex-

tend in a diagonal direction toward the ad jacent driving head at about an angle of forty-five degrees and are grouped in pairs, the members of each pair extending parallel to each other, and the pairs being equal in number to the number of driving arms.

In the preferred form of hoop driving mechanism as illustrated in the accompanying drawings, each driving head has eight driving arms 7 7 the outer end of each driving arm being pivoted between a pair of the lugs 68, by a pin. These driving arms extend horizontally toward the centering cone, and have their inner ends passing between two of the parallel radial arms 76, said inner ends being supported by rollers 78, mounted on pins extending transversely through the driving arms as shown in Figs. 15 and 18.

These rollers work on the diagonal surface of the arms 76, which are flat and smooth.

The inner ends of driving arms are drawn toward the center as the driving head moves toward the cone, by springs 79, encircling bolts 80, seated in the pockets 70, and having their outer ends passed through openings in the cross pieces 69, and in the driving arms, and are spread as the driving head moves away from the cone, by the rollers working upon the diagonal surfaces of the radial arms 76. Nuts are screwed upon the outer ends of the bolts 80, by means of which the tension of the springs 79, may be regulated.

A driving plate 81 is atlixed to the inner end of each driving arm by a bolt 82, so as to have a slight rocking motion on said bolt in order to adapt itself to the shape of the keg upon which hoops are being driven. The bolt 82, is locked against involuntary withdrawal by a longitudinal pin 83, seated in a depression in the arm and having a chisel edge which is adapted to be embedded in the end of the bolt. The pin 83, is moved to embed its point in the bolt by a set screw 8st, having a cone point which engages with the beveled opposite end of the pin, see Fig. 20. Each driving plate is formed so to have four driving edges, so that when one edge is worn, the plate can be given a quarter turn to bring a screw edge into use.

While the plates have a slight rocking motion, they are held against involuntary rotation on the bolt 82, by pins 85, seated in the ends of the driving arms and having their outer ends seated in depressions 86, in the adjacent faces of the plates. The pins are forced outwardly by coiled springs, 87, see Fig. 20. Small openings 88, lead from the depressions 86 to the outer surface of each plate, through which openings an instrument is introduced to push back the pin 85, against the tension of the spring when it is desired to turn the plate to bring a new driving edge into use.

The centering and shaping cones are forced into the open ends of the keg by a pair of forked levers 89, which are connected by a pair of coiled extension springs 90, see Figs. 1, 4, 5, 6 and 9. These levers 89, are pivoted by bolts at their lower ends to fulcrum blocks 91, secured by set screws to the lower tie rod 7, and about vertically below the centering cones when said cones are in their normal positions as shown in Figs. 1 and 4. The upper ends of the levers are forked, as shown at 92, and straddle the hubs 74E, of the cones, the edges of the forks seating against lugs 93, on the cones, see Figs. 1

and 9. A clip 94, having a forked portion and two laterally extending portions, straddles each lever 89, at a point about midway of its length, and a U shaped bar 95, has its ends screw threaded and passed through openings in the lateral portions of the clip being held in place by nuts. The coiled extension springs 90 have their ends connected to the inner ends of the U shaped bars 95, and tend to draw the levers 89 toward each other.

lVhile the centering and, shaping cones have a limited longitudinal DIOVGD'IQDl) on the bars 38 and 39, they are held against rotation on or displacen'lent from said bars by longitudinal rods 96, having their inner ends passed through slots in the driving heads and provided with eyes which hook over a vertical pin 9'7, in the hubs of the centering cones see Figs. 1 and at. The outer ends of the rods 96, pass through openings in the A shaped portion of the end frame member, and have cellars 9T, fastened thereon by set screws. The inward movement of the centering cones can be regulated by moving the collars to different points on the rods, the movement of the cones being stopped when the collars strike against the end frame members.

An adjustable support for the keg is pro vided, said support consisting of a pair of channel bars 98, which extend transversely across the center of the machine and are supported by adjustable brackets 99, bolted to the side frame members 3, see Fig. A ribbed plate 100, having a. horizontal rib on its inner surface and a vertical rib on its outer surface, is interposed between each of the brackets 99, and the side frame member; the horizontal rib fitting in a horizontal slot in the side frame members and the vertical rib fitting in a vertical slot in the brackets 99, the brackets and the plates being securely fastened to the frame members by bolts 101, see Figs. 1 and 10. By this means both a vertical and a horizontal adjustment of the barrel support: is provided.

Horizontally extending angle irons 102, are secured by screws to the upper portions of the brackets 99, so that they extend from the front and rear sides of the machine. lv'hen operating the machine, the operator places a keg upon the angle irons and rolls it into the place upon the bars 98, see Figs. 1 and d. V

The operation of the machine is as follows :The various parts of the machine being in the posit-ion shown in Figs. 1 and 4, the operator places the end and bilge hoops upon a keg and places said keg in position as above described. Then grasping the handle at the end of the lever 32, he moves it toward the machine, thereby rocking the shaft 30, and throwing in the clutch. This locks the pulley 20 to the driving shaft 8, and causes said shaft to revolve, which motion is transferred to the main shaft 18, by the pinion 10. spur gear 11, pinion .16 and spur gear 17. As the gear 17 and shaft 18 revolve, the eccentrics 4:0 and 41, rock the Illt) i will be seen that a levers 46 and 47 on their pivots and draw their upper ends toward each other and move the driving heads toward the keg. When this movement begins the coiled springs 90, impart a similar movement to the levers 89, and draw their upper ends toward each other thereby moving the centering cones toward the keg. As the cones enter the open ends of the keg, the ends of the staves are spread by the cone surfaces 71, until the ends of the keg are perfectly circular in form, the movement of the cones being stopped by the annular flanges 73, which drive the end hoops into place. It will be noticed that while the foregoing operation is being performed, the position of the cones relatively to the driving heads does not change, the cones and driving heads moving at equal speed. The cones are now firmly seated in the ends of the keg which is accurately centered between the driving heads. The continued movement of the driving hubs carries the driving arms 77, toward the keg, the inner ends of said arms closing around the barrel as the rollers 78, roll down thejnclined surface of the radial arms 76, until the driving edges of the driving plates contact with the staves when the continued inward movement of the driving heads drives home the bilge hoops.

By referring to Figs. 1, 4, l8 and 19, it series of collars 103, loosely encircle the bars 37 and 88, between the driving heads and the hubs of the centering cones. As the driving heads move toward the keg, they come into contact with these collars and exert an increased pressure on the cones, thereby driving the end hoops into place by means of the annular flanges 73. By increasing or lessening the number of collars, the pressure against the cones may be increased or reduced. The driving heads have now reached the limit of their inward movement and the hoops have been driven into place. The eccentrics now complete the remaining half of their revolution and the return stroke of the eccentric rods return the driving heads to their normal position. At the instant that the driving heads commence this return movement, the inner ends of the driving arms open or move away from the sides of the keg. This movement is caused by the rollers 78, rolling up the inclined surface of the radial arms 76, as the driving heads recede until said rollers seat in the outer hook ends of said arm. The arms 77, open against the tension of the spring 7 9, but the tension of the springs 90 is suflicient to overcome this tension and the cones remain in their position until the driving arms reach the limit of the outward movement when the cones are drawn back with the driving heads.

The object in providing movable fulcrums for the levers 46 and 47 is to allow machine frame,

for the inequalities in the sizes of kegs, caused by unequal shrinkage of the staves and also for inequalities in the sizes of the hoops. It is obvious that by using eccentrics to operate the levers a certain definite length of stroke will be had at each revolution of the main shaft 18. The object in this class of work is not to drive the hoops a certain distance upon the keg, but to drive them into place with a certain pressure. In this machine, this object is obtained by using fulcrums for the levers 46 and 47, which are movable against the tension of springs.

By referring to Fig. 4, it will be seen that when driving the hoops into place the hoops are driven until the driving pressure becomes greater than the tension of the springs 61, when said springs will give and the lower ends of the levers 46 and 47, with their fulcrums will move instead of their upper ends while the remaining portion of the stroke is completed.

It is obvious that by adjusting the nuts 63, and thus regulating the tension of the springs 61, the hoops can be driven upon the ke with a predetermined pressure.
